The rate of certain reaction is given by the following rate law:
At a certain concentration of and
, the initial rate of reaction is 4.0 × 10⁴ M/s. What would the initial rate of the reaction be if the concentration of
Answer : The initial rate of the reaction will be,
Explanation :
Rate law expression for the reaction:
As we are given that:
Initial rate = 4.0 × 10⁴ M/s
Expression for rate law for first observation:
....(1)
Expression for rate law for second observation:
....(2)
Dividing 2 by 1, we get:
Therefore, the initial rate of the reaction will be,
Answer:
E = 16 J
Explanation:
We have,
You put scruffy can run up to 2 m/s on his fastest days scruffy has a mass of 8 kg
It is required to find the maximum kinetic energy on his fastest days. If v is the velocity, then kinetic energy is given by :
Plugging all the values,
So, the maximum kinetic energy on his fastest day is 16 J.
